| (3) Nov. 23rd. Special castings made ( the Scandinavian belt-ing for this experiment was then in stock) March 15th. Clutch fitted and passed to Experimental Test Dept. Tests of this clutch have not been pushed forward owing to the success of the type in which the belting is formed in one piece. The considerable delay which has occured in this case appears to be due to the pressure of axle and other experiments. | ||
